I can only report that my Fold³ isnt misbehaving which is on Android 12 with Samsung One Ui 4.
As a process of elimination please try https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ will help to highlight if an app or theme etc is potentially causing issues.
And if then necessary https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to hook up to a Computer or insert your earphones to enter into recovery mode.
A factory reset would be the very very last resort.
You can send feedback via your Samsung Members app too.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help.
I have the same issue. It's quite frustrating. For some reason my Z flip 3 really likes/wants the edge lighting to be blue only 🙄
It's not the worst thing but I really hope it's fixed soon 🤞
When selecting "colour" choose the option at the bottom right (the multi coloured one) That will open a whole load of colour options. Select one you want and then click on "done". That makes the colour stick and won't turn blue again
